Description

Resource request method and user equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a resource request method and a user equipment.

Background

Currently, for an unlicensed frequency band, a sending-end device needs to monitor whether the unlicensed frequency band is occupied Before sending a signal, and the sending-end device can send the signal only if the unlicensed frequency band is not occupied, where the above monitoring process is generally called a Listen-and-avoid mechanism (Listen-Before-Talk, LBT).

In the prior art, when a User Equipment (UE) triggers a Buffer Status Report (BSR) to Report, if no uplink resource can transmit the BSR, the UE may trigger a Scheduling Request (SR) to transmit (for example, a Media Access Control (MAC) layer of the UE indicates a Physical (PHY) layer to transmit the SR).

However, after the UE triggers the SR transmission, the LBT procedure is performed to monitor whether the frequency used for SR transmission is occupied, and if the frequency is occupied, the SR transmission may fail, thereby increasing the failure probability of the SR procedure.

Disclosure of Invention

Embodiments of the present invention provide a resource request method and user equipment, so as to solve a problem in the prior art that a failure probability of an SR process is increased due to SR transmission failure caused by LBT.

In order to solve the technical problem, the invention is realized as follows:

in a first aspect, an embodiment of the present invention provides a resource request method, where the method includes:

acquiring first information under the condition that User Equipment (UE) triggers a Scheduling Request (SR);

the UE performs any action of the following according to the first information: at least one of stopping the timer and prohibiting starting the timer without at least one of increasing the count of the first counter and increasing the count of the second counter;

wherein the first information is used for indicating that the UE currently stops sending the SR; the UE cannot send the SR on the SR resource within the time length corresponding to the timer; the first counter is used for recording the sending times of the SR; the second counter is used for recording the number of times that the SR is stopped from transmitting.

In a second aspect, an embodiment of the present invention provides a user equipment, including:

an obtaining module, configured to obtain first information when the UE triggers a scheduling request SR;

an execution module, configured to execute any one of the following actions according to the first information acquired by the acquisition module: at least one of stopping the timer and prohibiting starting the timer without at least one of increasing the count of the first counter and increasing the count of the second counter;

In a third aspect, an embodiment of the present invention provides a user equipment, which includes a processor, a memory, and a computer program stored on the memory and operable on the processor, and when executed by the processor, the computer program implements the steps of the resource request method according to the second aspect.

In a fourth aspect, an embodiment of the present invention provides a computer-readable storage medium, on which a computer program is stored, where the computer program, when executed by a processor, implements the steps of the resource request method as described above.

In the prior art, after the UE triggers the SR, the UE starts an SR prohibit transmission timer (i.e. the timer mentioned above), and generally, the UE cannot transmit the SR on the SR resource until the timer expires. However, after the timer is overtime, the UE may perform an LBT procedure to monitor whether the frequency used for SR transmission is occupied, if the frequency is occupied, and if the frequency is occupied after the LBT procedure, if the frequency is occupied, the SR transmission may fail, and further the SR may not be immediately transmitted in the available SR resource, thereby generating an extra SR transmission delay and increasing a failure probability of the SR procedure failure. Meanwhile, because LBT causes SR transmission failure, the UE will add 1 to the count of the SR transmission number counter (i.e., the first counter), and after the count of the first counter reaches a threshold, the UE considers that the SR process has failed, therefore, because LBT causes SR transmission failure, continuous counting of the first counter is also caused, and thus the failure probability of SR process failure is increased.

In the embodiment of the present invention, when triggering an SR, a UE may perform any one of the following actions according to first information used for indicating that the UE currently stops sending the SR: at least one of not incrementing the count of the first counter and incrementing the count of the second counter, stopping the timer, and inhibiting starting the timer. Therefore, under the condition that the UE currently stops sending the SR, the UE reasonably controls the counter, so that the failure probability of SR process failure is reduced, and meanwhile, the UE can immediately send the SR in subsequent SR resources by suspending or prohibiting the timer from starting, so that the SR delay is reduced, and the failure probability of SR process failure is reduced.

The embodiment of the invention can be applied to the communication between the network equipment and the UE in the 5G communication system, or the communication between the UE and the UE, or the communication between the network equipment and the network equipment.

Fig. 1 shows a schematic diagram of a possible structure of a communication system according to an embodiment of the present invention. As shown in fig. 1, the communication system includes at least one network device 100 (only one is shown in fig. 1) and one or more UEs 200 to which each network device 100 is connected.

The network device 100 may be a base station, a core network device, a Transmission and Reception node (TRP), a relay station, an access Point, or the like. The network device 100 may be a Base Transceiver Station (BTS) in a Global System for Mobile communication (GSM) or Code Division Multiple Access (CDMA) network, or may be an nb (nodeb) in Wideband Code Division Multiple Access (WCDMA), or may be an eNB or enodeb (evolved nodeb) in LTE. The Network device 100 may also be a wireless controller in a Cloud Radio Access Network (CRAN) scenario. The network device 100 may also be a network device in a 5G communication system or a network device in a future evolution network. The words used are not to be construed as limitations of the invention.

The UE200 may be a terminal, which may be a wireless terminal or a wired terminal, which may be a device providing voice and/or other service data connectivity to a user, a handheld device with wireless communication functionality, a computing device or other processing device connected to a wireless modem, a vehicle mounted device, a wearable device, a terminal in a future 5G network or a terminal in a future evolved PLMN network, etc. A Wireless terminal may communicate with one or more core networks via a Radio Access Network (RAN), and may be a Mobile terminal, such as a Mobile phone (or "cellular" phone) and a computer with a Mobile terminal, for example, a portable, pocket, hand-held, computer-included or vehicle-mounted Mobile device, which exchanges languages and/or data with the RAN, and Personal Communication Service (PCS) phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), and the like, and may also be a Mobile device, a UE terminal, an Access terminal, a Wireless Communication device, a terminal unit, a Station, a Mobile Station (Mobile Station), a Wireless Communication device, a terminal unit, a Station, a Mobile Station (Mobile Station), or a Mobile terminal, A Remote Station (Remote Station), a Remote Station, a Remote Terminal (Remote Terminal), a Subscriber Unit (Subscriber Unit), a Subscriber Station (Subscriber Station), a User Agent (User Agent), a Terminal device, and the like. As an example, in the embodiment of the present invention, fig. 1 illustrates that the UE is a mobile phone.

Fig. 2 is a flowchart illustrating a resource request method according to an embodiment of the present invention, and as shown in fig. 2, the resource request method may include:

step 201: and under the condition that the UE triggers the SR, the UE acquires the first information.

In the embodiment of the present invention, the first information is used to indicate that the UE currently stops transmitting the SR, that is, the first information may also be considered to indicate that transmission of the SR is discarded. For example, since the transmission frequency of the SR is occupied, the SR transmission to be performed is discarded.

Optionally, in this embodiment of the present invention, the first information is indication information sent by a PHY layer of the UE to a MAC layer. For example, when the UE triggers BSR reporting, if there is no uplink resource to send the BSR, the UE triggers SR, and at this time, the PHY layer of the UE indicates the MAC layer "SR sending discarded indication".

Step 202: the UE performs any action of the following according to the first information: at least one of not incrementing the count of the first counter and incrementing the count of the second counter, and at least one of stopping the timer and inhibiting starting the timer.

In the embodiment of the present invention, the UE cannot send the SR on the SR resource within the time duration corresponding to the timer, that is, before the timer expires, the UE cannot send the SR on the SR resource. It should be noted that the timer in the embodiment of the present invention is an existing "SR prohibit transmission timer (SR-prohibit timer)".

The SR resource for transmitting the SR may be configured on one or more cells.

In this embodiment of the present invention, the first counter is used to record the number of SR transmissions. Note that, the first timer in the embodiment of the present invention is an existing "SR transmission number COUNTER (SR _ COUNTER)".

In the embodiment of the present invention, the second counter is used to record the number of times that the SR is stopped from being transmitted.

Exemplarily, in the embodiment of the present invention, in the case that the UE currently stops transmitting the SR, the UE solves different technical problems by performing different actions.

In a first possible example:

in the prior art, the above timer is started immediately after the UE triggers the SR, and the UE cannot send the SR on the SR resource until the timer expires. Since the LBT procedure is usually executed after the timer expires, at this time, if the UE performs the LBT to find that the transmission frequency for transmitting the SR is occupied, the UE still cannot transmit the SR after the timer expires, and further the SR cannot be immediately transmitted in the available SR resources, thereby generating an additional SR transmission delay.

To solve this problem, when the UE currently stops transmitting the SR, the UE in the embodiment of the present invention may perform the following operations on the timer: at least one of stopping the timer and prohibiting starting the timer is achieved, so that the UE can immediately send the SR in subsequent SR resources, the SR delay is reduced, and the failure probability of SR process failure is reduced.

For example, the operation of the stop timer mentioned above means: in case the timer has started, the UE stops the timer.

Illustratively, the operation of prohibiting the start of the timer is: in case the timer has not started, the UE refrains from starting the timer.

In a second possible example:

in the prior art, after the UE triggers the SR, an LBT procedure is performed to monitor whether a frequency for SR transmission is occupied, and if the frequency is occupied, SR transmission failure may be caused, and the SR transmission failure may add 1 to the count of the first counter. In general, after the count of the first counter reaches a threshold value, the UE considers that the SR procedure fails. Thus, the failure of SR transmission due to LBT also results in the continuous counting of the first counter, thereby increasing the failure probability of SR procedure failure.

To address this problem, in a case where the UE currently stops sending the SR, the UE in the embodiment of the present invention may perform at least one of the following actions: the count of the first counter is not increased and the count of the second counter is increased to reduce the failure probability of the SR process failure.

Illustratively, in case the first counter count is larger than the second threshold, the UE decides that the SR procedure fails, thereby initiating the random access procedure.

Illustratively, the second threshold may be predefined (e.g., specified by a protocol) or configured by the network device for the UE.

Illustratively, the UE in the embodiment of the present invention adds a new second counter for recording the number of times that the SR is stopped from transmitting, so as to distinguish the number of times that the SR is stopped from the number of times that the SR is successfully transmitted. Thus, in the case that the UE currently stops transmitting the SR, the UE may choose not to increase the count of the first counter, but only increase the count of the second counter, thereby avoiding the continuous increase of the first counter.

For example, the counting process of the UE incrementing the second counter may be: the UE increments the count of the second counter by 1. It should be noted that, the above count increased by 1 is only an example, and in practical applications, the increased number is not limited.

In the resource allocation method provided in the embodiment of the present invention, when the UE triggers the SR, the UE may execute any one of the following actions according to the first information indicating that the UE currently stops sending the SR: at least one of not incrementing the count of the first counter and incrementing the count of the second counter, stopping the timer, and inhibiting starting the timer. Therefore, under the condition that the UE currently stops sending the SR, the UE reasonably controls the counter, so that the failure probability of SR process failure is reduced, and meanwhile, the UE can immediately send the SR in subsequent SR resources by suspending or prohibiting the timer from starting, so that the SR delay is reduced, and the failure probability of SR process failure is reduced.

Optionally, the method provided in the embodiment of the present invention further includes the following steps:

step A1: the UE sends an SR to the network device.

Step A2: the UE resets the second counter.

Illustratively, after the UE transmits the SR, the UE needs to reset the count of the second counter, i.e., reset the count of the second counter to the initial value. For example, the count of the second counter is set to an initial value "0".

The specific execution timing of the above steps a1 and a2 is not limited in the present invention, and may be before step 201, after step 201, or after step 202.

In the embodiment of the invention, after the UE sends the SR to the network equipment, the UE indicates that the current SR sending of the UE is successful, at this time, the second counter can be reset, and the number of times of the SR sending of the UE is forbidden is counted under the condition that the UE is forbidden to send the SR next time, so that the counting accuracy of the second counter is improved.

step B1: and if the count of the second counter is greater than or equal to the first threshold, the UE adds 1 to the count of the first counter or judges that the SR process fails.

Illustratively, the first threshold described above may be predefined (e.g., specified by a protocol) or configured by the network device for the UE.

For example, the counting process of the UE incrementing the first counter may be: the UE increments the count of the first counter by 1. It should be noted that, the above count increased by 1 is only an example, and in practical applications, the increased number is not limited.

In the embodiment of the invention, when the count of the second counter is greater than or equal to the first threshold, that is, the number of times that the UE prohibits the SR transmission satisfies the threshold, the UE can reasonably control the first counter by increasing the count of the first counter, thereby reducing the failure probability of the SR process failure.

The first information is used to indicate that the UE300 currently stops sending the SR; the UE300 cannot send the SR on the SR resource within the duration corresponding to the timer; the first counter is used for recording the sending times of the SR; the second counter described above is used to record the number of times the SR is stopped from being transmitted.

Optionally, as shown in fig. 3, the UE300 further includes: a sending module 303 and a resetting module 304, wherein:

a sending module 303, configured to send the SR to the network device.

A reset module 304 for resetting the second counter.

Optionally, the execution module 302 is further configured to increase the count of the first counter or determine that the SR process fails if the count of the second counter is greater than or equal to the first threshold.

Optionally, the first threshold is predefined or configured by the network device for the UE.

Optionally, the first information is indication information sent by the physical layer of the UE300 to the MAC layer.

In the UE provided in the embodiment of the present invention, when the UE triggers the SR, the UE may execute any one of the following actions according to the first information used to indicate that the UE currently stops sending the SR: at least one of not incrementing the count of the first counter and incrementing the count of the second counter, stopping the timer, and inhibiting starting the timer. Therefore, under the condition that the UE currently stops sending the SR, the UE reasonably controls the counter, so that the failure probability of SR process failure is reduced, and meanwhile, the UE can immediately send the SR in subsequent SR resources by suspending or prohibiting the timer from starting, so that the SR delay is reduced, and the failure probability of SR process failure is reduced.

1. A method for resource request, the method comprising:

under the condition that User Equipment (UE) triggers a Scheduling Request (SR), a Media Access Control (MAC) layer of the UE indicates a physical layer of the UE to send the SR;

the UE executes a monitoring avoidance mechanism LBT process, and the physical layer sends first information to the MAC layer under the condition that the sending frequency of the SR is occupied;

wherein the first information is used for indicating that a transmission frequency of the SR is occupied; the UE cannot send the SR on the SR resource within the time length corresponding to the timer; the first counter is used for recording the sending times of the SR; the second counter is used for recording the number of times that the SR is stopped from transmitting.

2. The method of claim 1, further comprising:

the UE sends the SR to network equipment;

the UE resets the second counter.

3. The method of claim 1, further comprising:

and if the count of the second counter is greater than or equal to a first threshold, the UE increases the count of the first counter or judges that the SR process fails.

4. The method of claim 3, wherein the first threshold is predefined or configured for the UE by a network device.

5. A User Equipment (UE), comprising:

a sending module, configured to, when the UE triggers a scheduling request SR, instruct a physical layer of the UE to send the SR by a media access control MAC layer of the UE; the UE executes a monitoring avoidance mechanism LBT process, and the physical layer sends first information to the MAC layer under the condition that the sending frequency of the SR is occupied;

an execution module, configured to execute any one of the following actions according to the first information sent by the sending module: at least one of stopping the timer and prohibiting starting the timer without at least one of increasing the count of the first counter and increasing the count of the second counter;

6. The UE of claim 5,

the sending module is further used for sending the SR to network equipment;

the UE further comprises:

a reset module to reset the second counter.

7. The UE of claim 5,

the execution module is further configured to increase the count of the first counter or determine that the SR process fails if the count of the second counter is greater than or equal to a first threshold.

8. The UE of claim 7, wherein the first threshold is predefined or configured for the UE by a network device.

9. A user Equipment, UE, comprising a processor, a memory and a computer program stored on the memory and executable on the processor, the computer program, when executed by the processor, implementing the steps of the method according to any of claims 1 to 4.

10. A computer-readable storage medium, characterized in that a computer program is stored on the computer-readable storage medium, which computer program, when being executed by a processor, carries out the steps of the method according to any one of claims 1 to 4.
